Davies and Rennie determined that the instantaneous peak and mean power transferred to the center-of-mass of a subject during jumping could be calculated from analyzing the ground reaction force. Since Davies and Rennie's report, vertical jumping has been used to measure the peak and mean power transferred to the center-of-mass and to assess human performance. It has also been suggested that the external load a subject experiences effects the power production. However, it is difficult to determine if the difference in power production as defined in these studies is due to the external loading, or is an effect of changing the dynamics of the movement. In this paper, we describe a study which allows us to more clearly define the power developed during jumping under different weights, and the relationship between the power developed and jump height.
戴维斯和雷尼确定，通过分析地面反作用力，可以计算出受试者在跳跃过程中传递到质心的瞬时峰值功率和平均功率。自戴维斯和雷尼的报告发表以来，垂直跳跃一直被用于测量传递到质心的峰值功率和平均功率，并评估人类运动表现。也有人提出，受试者所承受的外部负荷会影响功率产生。然而，很难确定这些研究中所定义的功率产生差异是由于外部负荷，还是运动动力学变化的影响。在本文中，我们描述了一项研究，该研究使我们能够更清楚地定义在不同重量下跳跃时产生的功率，以及所产生的功率与跳跃高度之间的关系。
